Corrosion and Rust Prevention Strategies for Coal Storage Space Frame Structures

The coal storage space frame is a critical structural system used to support coal stockpiles in coal bunkers or coal yards. It is characterized by high load-bearing capacity and structural stability. However, during service, space frame structures in coal storage facilities are often subject to corrosion and rust, which can reduce their service life and load-carrying capacity and even pose safety risks. Therefore, effectively preventing corrosion and rust in coal storage space frames is essential for extending their lifespan and ensuring their structural stability and safety.

1. Selecting Appropriate Materials

First and foremost, selecting suitable materials is a key step in preventing corrosion and rust in coal storage space frames. In most cases, these frames are made of Q235 carbon structural steel, which is prone to atmospheric corrosion. To mitigate corrosion, LFBJMB selects high-performance steel materials specifically suited for coal storage environments. Additionally, advanced galvanizing processes are employed to enhance the protective coating on steel surfaces. This significantly improves the corrosion resistance of the structure and extends its operational life.

2. Enhancing Protective Measures

Strengthening protective measures is another effective method to prevent corrosion and rust. During operation, anti-corrosion coatings such as anti-rust paint or epoxy resin paint can be applied to the surface of the space frame. These coatings form a protective film that isolates the structure from coal dust, oxygen, and moisture, effectively preventing corrosion.

3. Controlling Environmental Factors

Considering the high-dust and high-humidity environment inside coal bunkers, LFBJMB offers tailored environmental improvement solutions. These include the design and installation of efficient ventilation and dust removal systems to reduce dust concentration, as well as the deployment of dehumidification equipment to control humidity levels. These measures help minimize the environmental factors that contribute to corrosion.

4. Strengthening Maintenance and Management

Reinforcing maintenance and management is also a crucial approach to corrosion prevention. In daily operations, it is necessary to establish a comprehensive maintenance management system with clearly defined responsibilities and maintenance cycles. Regular inspections, maintenance, and servicing should be conducted to detect and resolve issues promptly, ensuring the space frame remains in optimal condition. Additionally, technical treatments such as abrasive blasting and electroplating can be employed to remove rusted areas and further extend the structure’s service life.
